DescriptionSapstreak is a fatal disease of sugar maple that usually enters the tree through basal trunk scars or root wounds. The disease most often affects large, wounded trees left after logging. The fungus causing sapstreak readily infects stumps or cut logs during the summer months. So, wounding sugar maples during this time will increase the potential for disease spread. In the Lake States, sapstreak has only been found in a few areas of Michigan and at one location in Wisconsin. Although few trees have been killed by sapstreak, it has the potential to become a serious disease in sugar maple stands.
